Graphic card suggestions?

I have amd 6850 graphics card but I was thinking to buy something better and higher in specs and cost range to be something around 230-330 euros.. Any suggestions?
ps main reason for this is because i want to play gta5 and some other new games in a ''better'' graphical settings.

Thanks in advance.

For me i will just go for quality. :D

quality like... GeForce GTX 1080? ooh, I would go for that one

GTX 950. 1080 is out of OP's budget

I still run the GTX 970 and it still works like a charm for most big name games :)

Yup, GTX 970, all the way! :)
